Answer:

Gas

Explanation:

The properties of the three states of matter are:

solid : fixed shape, fixed volume, high density as the intermolecular forces are strong and the particles cannot move here there. Only vibrations are possible.

Liquid: Fixed volume but shape depends upon the container, density lower than solid but higher than air.

Gas: Not fixed volume and not fixed shape also. The density is least among the three states of matter. There are leas strong force of interactions between molecules. the thermal energy is highest among the three states of matter.

Thus answer is gas.

You have 350 mL of 3.4 M hydrochloric acid (HCl). How many grams of HCl gas are dissolved? Bonus: what is the volume of the HCl
Crank

Answer:

1. 43.44g of HCl

2. 26.67 L of HCl

Explanation:

1) Molarity of a solution = number of moles (n) ÷ Volume (V)

According to the provided information in this question,

V = 350 mL = 350/1000 = 0.350L

Molarity = 3.4 M

Using Molarity = n/V

3.4 = n/0.350

n = 3.4 × 0.350

n = 1.19mol

Using the formula below to calculate the mass of HCl;

mole = mass/molar mass

Molar mass of HCl = 1 + 35.5 = 36.5g/mol

mole = mass/MM

mass = 1.19 mol × 36.5g/mol

mass = 43.44g of HCl

2) At STP, HCl has a pressure of 1atm, a temperature of 273K

V = ?

n = 1.19 mol

R = 0.0821 Latm/molK

Using PV = nRT

V = nRT/P

V = 1.19 × 0.0821 × 273/1

Volume = 26.67L
